A graphic ROM 410 in which the graphic data read by the control of the main controller 200 and used as a background image when selecting a communication karaoke is compressed and stored;

The main controller 200 receives the MIDI data and the command, and outputs the appropriate accompaniment music.

Here, the CPU 100 performs control and data transmission and operation of the entire system according to the control signal of the main controller 200 by a program stored in the program ROM 110.

Data processing for peripheral function blocks in the CPU 100 is performed by an interrupt, and the function of transferring the various interrupt rolls to the CPU 100 necessary for system control is performed by the modem 300 and the main controller 200.

The interrupt request is generated by several tasks (TASK) inside the modem 300 and the main controller 200. The task is mainly generated when infrared data is received from a transmitter, or when data is received from an equation blanking time, an internal timer, or a TV microcomputer. The CPU 100 processes the task whenever an interrupt occurs.

The program ROM 110 stores programs and font data necessary for system operation, various decorating programs and data, and reads the corresponding contents from the CPU 100 to perform a series of operations thereon.

The main controller 200 is synchronized with an external video signal and generates a control signal for the entire system, a volatile memory 210 and a storage memory 220 control function constituting a memory means, and an external video synchronization signal. An impose function, a function of receiving infrared transmitter data input from an external transmitter and transmitting the same to the CPU 100, a function of recognizing the interrupt generated by the modem 300 and informing the CPU 100, a graphic and video control function, It transmits graphic data to the RAM DAC 230 and performs its own synchronization signal generation function.

In addition, it performs an interface function with the TV micom. When the CPU 100 transmits data to the TV micom, it converts the byte unit data into serial data and transmits the data to the TV micom. The CPU 100 reads the data by converting the data into parallel data.

The volatile memory 210 and the storage memory 220 each store read / write communication data, and the storage memory 220 does not lose the stored data even when the power is turned off.

The RAMDAC 230 stores the color data to be displayed on the screen in the internal pallet RAM. When the data is written by the CPU 100 and the pixel data of the screen is transmitted from the main controller 200, the corresponding pallet RAM is stored. The RGB data is read and converted into an analog RGB signal and output to an RGB switch (not shown).

The modem 300 demodulates the modulated signal received through the telephone line, detects and corrects an error, stores the data in an internal buffer, generates an interrupt in the CPU 100, and stores the currently received data in the memory means. 100) receives the digital data to be sent to the telephone line, modulates it, and sends it.

The program ROM 110 of the present invention should have a built-in program for performing a communication karaoke function, and the main controller 200 controls the graphic ROM 410 and transmits MIDI data and commands to the MIDI sound source 400. After the song data is received and stored in the memory 210, when one song data reception is completed, the song data is continuously moved to the storage memory 220 to be stored.

The MIDI sound source unit 400 required for the communication karaoke is to generate the appropriate sound by the control of the main controller 200 which has received and encoded the communication song data, and various commands and MIDI data in the form of serial data from the main controller 200. The accompaniment music is output by receiving.

The graphic ROM 410 compresses and stores graphic data used as a background image of a screen when selecting a communication karaoke, and the graphic data is a table in which a correspondence between lyrics contents and a background graphic among song data received from a host computer is tabled. The CPU 100 uses the graphic data of the graphic ROM 410 to represent a graphic image suitable for the song lyrics based on the information.

The communication karaoke function allows the user to sing the desired song in accompaniment by receiving the desired accompaniment and lyrics data (song data) from the host computer and outputting it.

2 is a flow chart of the present invention.

The present invention is the process of selecting a communication karaoke,

When selecting a communication karaoke to input a plurality of reserved song numbers to make a reservation;

When the reservation is completed, the process of switching to the TV mode and receiving the song data of the reserved song,

When the song data reception is complete, disconnect the line and select the karaoke function,

When the karaoke function is selected, the received reservation song data is sequentially played. If the karaoke function is not selected, the process is performed by executing the TV mode.

While receiving the song data of the reserved song, a message indicating that the reserved song is being received is displayed on one side of the television screen, and when reception of the reserved song is completed, it is displayed on one side of the television screen that the reception completion state is completed.

This invention will be described in detail with reference to the flowchart of FIG.

First, the information television is selected as the communication karaoke mode (step S1).

The communication karaoke mode selection method is as follows: First, the method of selecting using the numeric keys on the information service main menu screen.

Second, there is a method of selecting by pressing a karaoke key provided separately to the transmitter.

The first method is to select karaoke mode, a submenu of the communication main menu.

The second method is to press the karaoke key directly to select. In either case, if the karaoke mode is selected in step S1, the line is connected. If the karaoke is not selected, the routine exits.

Here, the line connection means connecting to a host computer which transmits song data by calling a predetermined value-added network operator.

When the communication karaoke is selected and the line is connected, the user views the karaoke menu screen and reserves a plurality of (N) song numbers (step S2).

The reserved song number is entered by the user using the numeric keys of the transmitter.

The song number is distributed to the user in the form of a booklet in advance, and new new songs are continuously input to the host computer, and a book containing the new song information is distributed to the user for a predetermined period (about 1 month).

Therefore, the user may look at a book distributed in advance and input a desired number of reserved songs.

A plurality of reserved song number inputs are reserved until the completion of reservation is checked in step S3.

If it is determined that the reservation is completed in step S3, the reserved song number is transmitted to the host computer.

The song data transmitted from the host computer is received (step S4).

When reception of reserved song data starts, the information television is switched to the television mode (step S5).

A message receiving message indicating the reception of song data is displayed on one side of the television screen so that the user can recognize that the reserved music is being received while the television user is watching the television screen.

In the state of switching to the television mode, the song data of the reserved song is received and it is checked whether the data reception is completed (step S6).

Here, the reception of song data means that the reception of song data for all reserved songs is completed.

Song data for one song during communication karaoke operation is received by 1 byte per modem interrupt and each time received by 1 byte without error is sequentially stored in the volatile memory 210 when the song data for one song received without error The song data stored in the volatile memory 210 is read and decorated and stored in the storage memory 220.

The reason why the song data stored in the volatile memory 210 is transferred to the storage memory 220 is stored in the first embodiment. To save it temporarily after every time interrupt,

Secondly, in order not to lose stored data even in case of power failure.

Third, although there are differences depending on the capacity of the storage memory 220, it is to directly read and output the songs stored in the storage memory 220 without receiving a number of favorite songs in the communication mode.

The song data for one reserved song is stored in the volatile memory 210 and then transferred to the storage memory 220, and the song data of the next song is stored in the volatile memory 210. Before the song data reception for the reserved song is completed, a reception completion message indicating completion of data reception is displayed on one side of the TV screen (step S7) and the line is disconnected (step S8).

At this time, a television screen is displayed, and the song memory for the reserved song is stored in the storage memory 220.

In this state, the user selects whether to continue watching the TV screen or use the karaoke function by using the transmitter (step S9).

If the user wants to watch television, the TV screen is continuously displayed (step S10). If the karaoke function is selected, the received song data is sequentially reproduced in the order of reservation (step S11).

When the step S11 proceeds, the screen displays one of the background screens stored in the graphic ROM 410.

Such invention according to the present invention, when pre-booking of a plurality of reserved songs in the information karaoke selection of the information TV receives the song data of the reserved songs in the state of switching to the TV mode, when the data reception of all the reserved songs is finished, check the karaoke function selection to karaoke When the function is selected, the song data is played in the reserved order. If the karaoke function is not selected, the TV mode is continued.
